Grimmy,
I have to agree with Vance. The 45 degree thing is a basic guideline. On really thin branches such as these, you can run the wire along the branch more. Especially when using relately thick wire.
That top "anchor" is an absolute mess.
The branches are shaped like rainbows. Not what we want. The downward bend should be right at the connection point with the trunk.
Here are a couple pages on wiring. There's more, when I get home I'll attach them.
The Figure 8 technique, only needs to be done on really heavy branches. The branches on Grimmy's tree don't need it.
The second page shows ways to avoid the "rainbow".
See Figure 16? I used that technique to bend the bottom lower branch on this pine down:
The guy wire wasn't used to pull it down. It's there to hold it. The rebar was used to do the pulling. The guy wire was placed in position, then tightened to hold it. That way, you can use thin guy wires.
Edited to add: I didn't know that was insulated wire. It looks like the black aluminum. I have no way of knowing if the wire inside is thick enough for the job.
